The systolic blood pressure (given in millimeters) of males has an approximately normal distribution with mean u = 125 and standard deviation o = 12. (a) Calculate the z-scores for the male systolic blood pressures 110 and 140 millimeters. (Round your answers to two decimal places.) 110 mm z = 140 mm z = (b) If a male friend of yours said he thought his systolic blood pressure was 2.5 standard deviations below the mean, but that he believed his blood pressure was between 110 and 140 millimeters, what would you say to him? (Enter your numerical answer to the nearest whole number.) He is ---Select--- because 2.5 standard deviations below the mean would give him a blood pressure reading of millimeters, which is ---Select--- the range of 110 to 140 millimeters.

Interpret a P-value: The manufacturer of a medication designed to lower blood pressure claims that the mean systolic blood pressure for people taking their medication is less than 135. To test this claim, blood pressure is measured for a sample of 500 people who are taking the medication. The P-value for testing Ho: μ = 135 versus H₁: µ< 135 is P = 0.001. a. The manufacturer concludes that because the P-value is very small, we can be fairly certain that the mean pressure is less than 135, but we cannot conclude that it is a lot smaller. Is this conclusion justified?
Calcium levels in people are normally distributed with a mean of 9.7 mgdL and a standard deviation of 0.5 mgdL . Individuals with calcium levels in the bottom 10% of the population are considered to have low calcium levels. Find the calcium level that is the borderline between low calcium levels and those not considered low. Carry your intermediate computations to at least four decimal places. Round your answer to one decimal place.
